[NLRS] Kuhne 10 GHz transverter kit question

[Dr. Gerald N. Johnson]

I think nearly all the components are SMT, but from a decade old design 
are probably at least 0805 or larger. It is a working design, as is the 
DEMI. It takes a detector or power (milliwatts) meter to tune the 
multiplier and transmitter and some sort of signal source to tune the 
receiver side. A 2m hand held driving a diode and antenna can be the 
signal source. Diode should be 1N23 or HSMS8202 family. 146.03 x 71 is 
10368.130. 144 * 72 would be 10368.0 but that's also the IF where you 
are trying to hear and the hand held will hide the converted microwave 
signal. If there is tuning and matching before the first RF stage on 
receive, it will benefit from tuning for the best NF. One suitable noise 
source I published in
www.geraldj.networkiowa.com/papers/2012/predictablenoiseA.pdf and manual 
NF measuring in
www.geraldj.networkiowa.com/papers/2012/Intermod2.pdf
Alternatively an automatic NF test set will allow significantly faster 
adjustment but the acquisition cost will pay for several years of manual 
NF measurements and tweaks.

There was an article in DUBUS several years ago about the experiences of 
building the KB6NT transverter kit. It will take a while of rooting to 
find that.

I was thinking of taking advantage of Jim's club order to finally get on the band.  If other's were thinking of doing this, how about a couple of group build weekends?
